Punarnava was observed by some villagers to spring back to life after being a dead dry plant and thus named the Renewer. Puna means Again and Nava means New. So it rejuvenates the cells rather than only eliminating water from the body. So it is useful even where the cells are damaged. INGREDIENTS: Each capsule contains 500mg standardized extract of Herb - Punarnava (Boerhavia diffusa).
